Belkin N Wireless router

I am trying to setup my new wireless router. I have Dell laptop and E-machine desktop. Running Windows XP on both. According to lights router is working correctly, but when I run the setup assistant on the laptop during step 1 I get this message: "The Setup Assistant is not able to connect to the Router via any of the network adapters in this computer. Please go back to the Quick Installation Guide and make sure all physical connections are correct. Also, please powere cycle the Router and make sure that the Router has power and that the appropriate lights are on(see guide)", which I have done several times with no success. Any suggestions?
